求 Golang 中复数的反双曲余弦
原文:https://www . geeksforgeeks . org/find-the-reverse-双曲线余弦复数 in-golang/
Go 语言借助 cmplx 包，为复数的基本常数和数学函数提供内置支持。允许你借助 math/cmplx 包提供的 Acosh()函数求指定复数的反双曲余弦。因此，您需要在 import 关键字的帮助下在程序中添加一个 math/cmplx 包来访问 Acosh()函数。
语法:
func Acosh(x complex128) complex128
让我们借助给定的例子来讨论这个概念:
例 1:
// Golang program to illustrate how to find the
// Inverse Hyperbolic Cosine of Complex Number
package main
import (
"fmt"
"math/cmplx"
)
// Main function
func main() {
// Finding inverse hyperbolic cosine
// of the specified complex number
// Using Acosh() function
res_1 := cmplx.Acosh(2 + 5i)
res_2 := cmplx.Acosh(-9 + 8i)
res_3 := cmplx.Acosh(-5 - 7i)
// Displaying the result
fmt.Println("Result 1:", res_1)
fmt.Println("Result 2:", res_2)
fmt.Println("Result 3:", res_3)
}
输出:
Result 1: (2.3830308809003298+1.1961255219693694i)
Result 2: (3.181316253686062+2.4132370433090795i)
Result 3: (2.8462888282083862-2.18786062347089i)
例 2 :
// Golang program to illustrate how to find the
// Inverse Hyperbolic Cosine of Complex Number
package main
import (
"fmt"
"math/cmplx"
)
// Main function
func main() {
cnumber_1 := complex(2, 3)
cnumber_2 := complex(6, 8)
// Finding inverse hyperbolic cosine
cvalue_1 := cmplx.Acosh(cnumber_1)
cvalue_2 := cmplx.Acosh(cnumber_2)
// Sum of two inverse hyperbolic cosine values
res := cvalue_1 + cvalue_2
// Displaying results
fmt.Println("Complex Number 1: ", cnumber_1)
fmt.Println("Inverse hyperbolic cosine 1: ", cvalue_1)
fmt.Println("Complex Number 2: ", cnumber_2)
fmt.Println("Inverse hyperbolic cosine 2: ", cvalue_2)
fmt.Println("Sum of inverse hyperbolic cosines : ", res)
}
输出:
Complex Number 1: (2+3i)
Inverse hyperbolic cosine 1: (1.9833870299165355+1.0001435424737974i)
Complex Number 2: (6+8i)
Inverse hyperbolic cosine 2: (2.9964401392355113+0.9296901439918359i)
Sum of inverse hyperbolic cosines : (4.979827169152047+1.9298336864656334i)
